The search results
The police saw that Tim owned a BB cannon and that he had a stock of pellets. Upon checking if Tim had any previous records, it was evident that he could be a prime candidate as the shooter. However, they still did not find enough proof to arrest him yet for the case of animal abuse.

When Hayden heard about Tim, she was speechless. She did not know this particular neighbor well and she could not think of any reason why Tim would want to hurt Jackson. Tim was the sole suspect for the animal abuse. This was based on his notorious background and the fact that he owned a BB cannon and had a stock of pellets in his home. However, there was little forensic evidence to implicate him for shooting Jackson.
